Battery Information
Improper battery selection, use, installation and care
are the cause of numerous wireless system failures.
Alkaline Batteries: Alkaline batteries such as
Mallory’s DURACELL® or Eveready’s ENER-
GIZER® provide the most reliable operation in
wireless transceivers. Typical battery life of fresh al-
kaline batteries is 12 hours. The use of low cost
carbon-zinc batteries is NOT recommended.
Nickel-Metal Hydride Batteries: These batteries
can save you money in the long run, as they can be
recharged. Typical battery life is 8 to 9 hours, which
is about 70% of the length of time alkaline batteries
last.
